New Delhi: On 6th December, the Central Pollution Control Board (CPCB) which monitors the water quality of the Yamuna river and drains discharging into the it, raised concern over frothing and pollution in the river, stated the Ministry of Environment, Forest & Climate Change (MoEFCC) in a press communication. In the past, the CPCB has observed froth formation and increase in ammonia levels in the Yamuna because of discharge of untreated sewage, non-operation of existing sewage treatment plants, improper functioning of effluent treatment plants (ETPs) installed by the industries and common effluent treatment plants (CETPs) located on the banks of the river.
The Monitoring of 22 drains was carried out recently where the CPCB found 14 drains (Sonia Vihar, Najafgarh, Shastri Park, Shahdara, and others) untapped and discharging sewage according to a CPCB statement. While five drains are 100% tapped and no flow at downward of interception observed, two drains were found tapped but overflow into the Yamuna was observed. One drain (drain no. 14) has no flow at all. Due to partially/untreated discharge of sewage and industrial effluent containing phosphorus, many times, foaming is also observed.
According to an official statement, the CPCB, taking cognisance of the matter, issued directions to Delhi Jal Board to submit a time-bound action plan to ensure compliance to norms by STPs and that no untreated sewage is discharged to these drains. The Delhi Pollution Control Committee (DPCC) has been directed to take action against the non-complying common effluent treatment plants (CETPs) and industrial units. Similar directions have also been issued to the State Pollution Control Boards of Haryana and Uttar Pradesh.
In view of the importance of the issues, reminders have been issued this week to the concerned agencies to submit the action taken report by 15th December, stated the Environment Ministry.
